Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Average AM and PM Subject-reported 12-hour Reflective Total Nasal Symptom Score ( rTNSS) Over the 14-day Treatment Period | Baseline and day 14 | The Reflective Total Nasal Symptom Score (rTNSS) was assessed by 12-hour reflective scoring of the severity of four nasal symptoms (rhinorrhea, sneezing, nasal congestion, nasal itching). Scores ranged from 0 (no signs/symptoms evident) to 3 (severe signs/symptoms that is hard to tolerate, causes interference with activities of daily living and/or sleeping). Each of these four nasal symptoms (rhinorrhea, sneezing, nasal congestion, nasal itching) of the rTNSS is rated on a scale from 0 to 3 (0 = none, 1 = mild, 2 = moderate, 3 = severe). The four nasal symptoms of the rTNSS is summed. The total score of the rTNSS ranged from 0 to 12. |

|---|---|---|
| Change From Baseline in Average AM and PM Subject-reported 12-hour Instantaneous Total Nasal Symptom Score (iTNSS) Over the 14-day Treatment Period. | Baseline and day 14 | The instantaneous Total Nasal Symptom Score (iTNSS) was assessed by instantaneous (ie, an evaluation of the symptom severity just before taking study medication \[within 10 minutes\]) of four nasal symptoms (rhinorrhea, sneezing, nasal congestion, nasal itching). Scores ranged from 0 (no signs/symptoms evident) to 3 (severe signs/symptoms that is hard to tolerate, causes interference with activities of daily living and/or sleeping). Each of these four nasal symptoms (rhinorrhea, sneezing, nasal congestion, nasal itching) of the iTNSS is rated on a scale from 0 to 3 (0 = none, 1 = mild, 2 = moderate, 3 = severe). The four nasal symptoms of the iTNSS is summed. The total score of the iTNSS ranged from 0 to 12. |
| Change From Baseline in the Overall Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) Score on Day 15 (Visit 4) | Baseline and day 15 | The PRQLQ is a validated, disease-specific, quality-of-life (QOL) questionnaire developed to measure the physical, emotional, and social impairments that are experienced by children (aged ≥6 to \<12 years) with rhinoconjunctivitis. The PRQLQ has 23 questions in 5 domains (nose symptoms, eye symptoms, practical problems, activity limitation and other symptoms). Subjects recall how they have been during the previous week and respond to each question on a 7-point scale with scores ranging from 6 (extremely bothered), 5 (very bothered), 4 (quite bothered), 3 (somewhat bothered), 2 (bothered a bit), 1 (hardly bothered at all), 0 (not bothered). The Overall PRQLQ score is the mean of all 23 subject-reported responses. The Overall PRQLQ score range from 0 to 6 where 0 represents no impairment and 6 represents maximum impairment. |
| Change From Baseline in Average AM and PM Subject-reported 12-hour Reflective Total Ocular Symptom Score (rTOSS) Over the 14-day Treatment Period. | Baseline and day 14 | The Total Ocular Symptom Score (TOSS) will be calculated using the 3 eye-related non-nasal symptoms: itching/burning eyes, tearing/watering eyes, and redness of eyes. The subject will assess and report his/her non-nasal symptoms twice (AM and PM assessments). Scores ranged from 0 (No sign/symptom evident), 1 (Sign/symptom clearly present but minimal awareness; easily tolerated), 2 (Definite awareness of sign/symptom that is bothersome but tolerable) and 3 (Sign/symptom is hard to tolerate; causes interference with activities of daily living and/or sleeping). The Total Ocular Symptom Score (TOSS) ranged from 0 to 9. |
